Concept explainers
(a)
Interpretation:
Boiling of water to become steam has to be classified as either a physical change or a
Concept Introduction:
Physical change:
A change in which no new substances are formed is said to be physical change. It affects the chemical substance but not its composition.
Chemical reaction:
It is a process that involves rearrangement of the molecular or ionic structure of a substance. In this, one or more chemicals reacts and forms other chemical compounds.
(b)
Interpretation:
Butter becoming rancid has to be classified as either a physical change or a chemical reaction.
Concept Introduction:
Refer to part (a).
(c)
Interpretation:
Burning of wood has to be classified as either a physical change or a chemical reaction.
